Information for users

Main implementations

Right now, we include the following Ruby implementations in Gentoo.

  • ruby19 - Ruby MRI 1.9 (deprecated)
  • ruby20 - Ruby MRI 2.0
  • ruby21 - Ruby MRI 2.1
  • ruby22 - Ruby MRI 2.2 (testing)

Experimental implementations

The following implementations need an active maintainer. They are currently available in the tree, but are unsupported. Ping us, if you want to help out!

  • jruby - JRuby (based on the Java Virtual Machine)
  • rbx - Rubinius

This graph shows the current distribution of Ruby implementations in Gentoo.

Activating specific implementations

You can activate specific ruby implementations by adding RUBY_TARGETS="$implementation" to /etc/portage/make.conf. Please note that you might overwrite the implementations set by base profile.

FILE /etc/make.conf
# Installs packages for Ruby 2.0, Ruby 2.1, and Ruby 2.2
RUBY_TARGETS="ruby20 ruby21 ruby22"

You can install multiple Ruby implementations in parallel. The RUBY_TARGETS variable picks the implementations from USE_RUBY (which is set in the ebuild) and installs these.

The base profile currently activates Ruby MRI 2.0 and Ruby MRI 2.1. Our recommendation is to run Ruby packages with Ruby MRI 2.0 per default.

You can eselect it via:

root # eselect ruby set ruby20

Using a testing implementation on a stable system

Starting with Ruby 2.2 we are now using the stable mask mechanism to keep Ruby 2.2 on testing until it is ready to be unmasked. If you want to use ruby22 on an otherwise stable system then please see the instructions for Python for now, using ruby_targets_ruby22 for the USE flag.

Information for developers

To ease maintenance of Ruby-based packages we currently provide several eclasses:
